A bucket elevator consists of a series of uniformly fed buckets mounted on an endless chain or belt which operates over head and foot wheels. The buckets are used to elevate (usually vertically) pulverized, granular, or lumpy materials. The material is received at the boot, raised and then discharged by passing over the head wheel at the top, into a discharge chute. Generally this mechanism is enclosed in a casing, especially the head and foot sections. Some elevators are self-supporting, but more often they are supported by, or at least braced against, a structural steel frame. Bucket elevators will be discussed under the seven headings listed below. Inclined elevators, which were seldom enclosed, were popular for handling crushed stone, but because of OSHA regulations, will probably go out of use (see figure 3.1).
